| Summary: | Bitumen (asphalt) is a petroleum based material which is used as binder in flexible pavement and bitumen has severe adverse impact on environment as well as in living being. Due to the limitation of petroleum, increased price and the impact on the environment, research is going on to find an efficient, cost effective and environment friendly alternative binder to replace the bitumen. This paper provides a review about the probable materials that can be used as an alternative binder where most of them are bio-based material and waste materials like bio-oil, plastic, polymer, waste cooking oil, waste tire rubber etc. Researchers have found some positive result with these materials. Further research is needed to make these satisfactory replacement of bitumen in industrial scale which will lead to a sustainable source of binder for flexible pavement. |
